Having experienced apotheosis, I can state that it is the only way to know you have found something new.
My seeking found what people call God.
That experience is personal and I have absolutely no way to prove this.
The God I found was natural and where our spiritual side might visit.
I do not posit an entity that is immortal. Just see it as an extension of the substance or material dualism thinking that most of us have.
